490 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 84 



I shall never forget my very pleasant acquaintance with Dr. 

 Ecluardo Liceaga, the President of the Superior Board of Health of 

 Mexico and the personal physician to President Porfirio Diaz. Tak- 

 ing advantage of a trip to Mexico in 1902, I made an effort to study 

 the geographic distribution of the yellow fever mosquito in that 

 Republic. I called on Doctor Liceaga in the City of Mexico, knowing 

 that he had accepted the conclusions of the United States Army Yel- 

 low Fever Commission and had instituted antimosquito work through- 

 out at least a part of the Republic. I was cordially received and given 

 letters o£ introduction. Doctor Liceaga told me with great pride of 

 the organization he had brought about, and mentioned the number of 

 inspectors he had appointed at different points. I was especially inter- 

 ested in the progress of the yellow fever mosquito from Vera Cruz 

 at sea level, through various towns, higher and higher quite to the 

 C^ity of Mexico itself at an elevation of over 8,000 feet. Doctor 

 Liceaga told me especially of his numerous inspectors at Orizaba and 

 Cordoba (towns on the railroad between Vera Cruz and the City of 

 Mexico). My subsequent visits to these towns indicated that, while 

 these inspectors were probably on the pay roll, they were not func- 

 tioning ; although I did meet a physician in Cordoba who told me that 

 he had once seen a lone Indian with a sign on his cap who carried a 

 quart can of kerosene! Later Doctor Liceaga attended the Pan 

 American Medical Congress at Washington at which I had the plea- 

 sure of first meeting Finlay and Guiteras. 



And by no means must I omit mention of Dr. C. Bonne and his 

 charming wife, Dr. C. Bonne-Wepster, whose great volume on the 

 mosquitoes of Surinam was published in Amsterdam in 1925. They 

 began to correspond with us in 1916, and in 1919 came to Washington 

 and spent many happy weeks with us. They were young, enthusiastic, 

 and did admirable work. Doctor Bonne's high standing in matters of 

 general sanitation gave the work a medical authority that has been 

 lacking in many mosquito papers. From Washington, they went to 

 England and studied in the British Museum, and then returned to 



mentioned in our earlier section on Brazil, has done some admirable work under 

 this Institute, and Dr. Cesar Pinto has become known as a worker of great 

 merit. In the current number of the Memorias (that for March, 1930) each 

 of these writers has an article. 



Just as this book goes to the printer I have received a large, two-volume 

 work by Doctor Pinto entitled (translated) "Arthropod Parasites and Trans- 

 mitters of Disease." The two volumes arc admirably illustrated and cover 845 

 pages. Unfamiliar as I am with the Portuguese language, it seems to me that 

 these two volumes cover the field more thoroughly and more satisfactorily than 

 any work on the same subject hitherto published.
